Title: Solar battery
Inventor: TAKAMORI NOBUYUKI
IPC: H01L31/078
Filed: 1984-10-11
Abstract: PURPOSE:To improve the photoelectric conversion efficiency while increasing shortcircuited photocurrent by a method wherein light receiving surface side of a semiconductor substrate with P-N junction is coated with an n type TiO2 film to constitute a solar battery. CONSTITUTION:n type impurity is diffused in one main surface of p type silicon substrate 1 to form a P-N junction 2. An n<+> type layer 3 further diffused with n type impurity is coated with an n type TiO2 film 7. The TiO2 film 7 is re duced to convert itself from an insulating material to a semiconductor resultant ly forming a hetero junction of n-TiO2/n-Si. Through these procedures, light receiving surface side electrodes 8 may be formed on the surface of converted n type TiO2 layer 7 to pick up the power generated from the space between the electrodes 8 and a backside electrode 4 formed on the p type silicon sub strate 1 side.

Abstract: PURPOSE:To manufacture an organic photoconductive medium having high photoconductivity and excellent wavelength dependency by simply forming a photoconductive organic layer on the surface of a desired fine irregular shape only by previously forming said shape to a substrate. CONSTITUTION:The photoconductive organic compound of a pigment compound, one molecule of which has a hydrophilic section, a hydrophobic section and a pigment section, is shaped onto the surface of a substrate with an arbitrary fine irregular shape as a photoconductive layer. A desired photoconductive organic compound is dissolved to a solvent such as chloroform, benzene, acetonitrile, etc., and developed onto a water tank 1 and the photoconductive organic compound is formed to a filmy shape, and the developing layer is limited by a diaphragm (or a buoy) 3 so that the developing layer does not diffuse freely and spread excessively on the water tank, thus acquiring surface pressure pi proportional to the state of the aggregate. The diaphragm 3 is moved, a developed area is reduced and the state of aggregate of a filmy substance is controlled, surface pressure is increased gradually, and the vertical elevating and lowering operation of a clean substrate 2 are repeated quietly, setting and maintaining surface pressure pi proper to the manufacture of the film, thus forming accumulated films in desired monomolecular accumulated number.

Title: Circular arc approximation method
Inventor: HIRAI KENICHI
IPC: G05B19/4103
Filed: 1983-11-14
Abstract: PURPOSE:To attain the circular arc approximation having equal approximation accuracy at any part by using a circular arc group to give approximation to an original curve while setting the difference of distance between the intersecting point between normal lines and the start and end points of a curve and the start and end point at the value equal to an approximation allowance error. CONSTITUTION:A curve separating part 1 produces short curves from an original curve. A normal line intersecting point calculating part 2 calculates the intersecting points between the normal lines at the start and end points of a separated curve. Then a comparing part 5 compares the differences delta of distance between the start and end points obtained at P0Q and PQ calculating parts 3 and 4 respectively and the intersecting point of the normal lines with the prescribed approximation allowance error epsilon. Then an indication is given to the part 1 to separate a long curve from the original curve when delta<epsilon is satisfied. While the data on the approximate circular arc is delivered from a circular arc data output part 6 in the case of delta>=epsilon. Furthermore the part 6 gives an indication to the part 1 to perform new separation with the end point of the obtained data defined as a start point. Then the new data is delivered. Hereafter this procedure is repeated.

Abstract: PURPOSE:To keep the oil temperature at a fixed level regardless of the quantity and the temperature of the applied load material, by delivering the heating output to its full limit for a certain following period according to the changing degree of temperature and only when the output of a temperature-sensitive element is reduced. CONSTITUTION:The temperature at the bottom of a pan 3 is detected by a temperature-sensitive element 2, and the oil temperature is detected by a temperature detecting means 4. For the temperature information, a heating output proportional to the temperature is generated by a heasting output control means 6. Then the oil temperature is controlled to a fixed level and then a load is thrown into the oil. A negative temperature gradient detecting means 5 decides a negative temperature slope in case the temperature of the element 2 is lowered although the heating output is equal to or larger than the preceding output. Then a full-limit output period is decided by a converting means 7 of negative temperature gradient 1 period of output at full gate opening and according to the degree of the slope. Then a heating device 1 is driven. Thus it is possible to keep the oil temperature at a level before the load is thrown into the oil.

Patent JP-H1052075-A (JP)
Title: Ultrasonic motor
Inventor: TSUKUI MICHIO
IPC: H02N2/00
Filed: 1996-07-26
Abstract: PROBLEM TO BE SOLVED: To provide an ultrasonic motor that allows the vibration of a piezoelectric transducer to be converted into the rotational motion of rotors with high efficiency. SOLUTION: A large number of slits 6a, 8a are formed on the surface of a rotor 8 in contact with a piezoelectric transducer. This makes it possible to make good use of even the vibration of the surface of the rotor 8 in contact with the piezoelectric transducer arising from the vibration (elliptic motion) of the piezoelectric transducer to increase the contact surface speed. It also makes it possible to convert the vibration of the piezoelectric transducer into the rotation of the rotor 8 and take it out. Slits 6a, 8b are formed on the surface of the piezoelectric transducer in contact with the rotor as well so that the piezoelectric transducer will be in a comb shape, that is, so that the teeth of combs will be in contact with each other.  This synergistically amplifies the vibration, and makes it possible to convert the vibration into the rotational motion of the rotor and take it out with higher efficiency.
